Concerning Rise in Threatened Native Bee Varieties In the European Continent

The total of non-managed bee varieties in Europe confronting extinction has more than doubled during the previous ten-year period, and the total of at-risk butterfly species has nearly doubled.

This dire scenario for crucial pollinating species was unveiled by scientific studies for the International Union for Conservation of Nature (IUCN) red list, which determined that at least 172 bee types out of nearly two thousand were facing extinction in European nations.

The total of butterfly types facing extinction in European nations has grown from thirty-seven to sixty-five since the earlier research, performed 14 years ago. A single species, the large white of Madeira (Pieris wollastoni) has now been declared extinct.

Apart from their beauty and cultural value, pollinating insects like bees and butterflies are essential supports for our well-being, our food supplies and our financial structures – sustaining the fruits, veggies and seeds that sustain us,” commented Grethel Aguilar. “The latest assessments of the European red list reveal major obstacles, with dangers increasing for butterflies and vital wild bee types.”

The reasons of the swift recent drops are the continuing harm or degradation of living environments caused by farming intensification and abandoned land, wetland drainage, overgrazing by livestock, and the use of pesticides and fertilisers including neonicotinoid chemicals. The breaking up of pollinator-friendly habitat substantially boosts the threat of disappearances in specific areas.

Global warming is also demonstrated to be a primary risk: Fifty-two percent of all endangered butterflies in Europe are endangered by the climate emergency – about double the number as a previous decade.

Nearly ninety percent of blooming plants in European nations depend on animal pollination, as stated by Dr Denis Michez. “Regrettably, non-managed bee groups are in severe drop and cannot readily be substituted by managed bee colonies,” he said. “If wild bees vanish, many wild plants might be in danger as well – of which flower-rich meadows and lovely orchid types are just a couple of instances.”

Fifteen types of bumblebees, which perform a vital function in pollinating crops such as peas, beans, peanuts and clover, and fourteen varieties of cellophane bee types, famous for aiding tree pollination such as willows and red maples, are now listed as threatened. Simpanurgus phyllopodus, a mining bee species found only in the continent and the single type of this genus group in Europe, is now classified as severely threatened – the research category nearest to disappearance in the wild.

Butterfly types that are solely present on high-altitude areas are highly susceptible to climate change as they have to climb upward as their habitats become hotter but eventually run out of space. In southern Spain, the Nevada grayling butterfly and the Andalusian anomalous blue butterfly are among above 40 percent of types unique to Europe (exclusive to Europe) at risk of extinction.

In the Mediterranean area, varieties such as the highly at-risk grayling of Karpathos are threatened by severe dry conditions and fires.

In the meantime, in the Arctic region, global heating is resulting in the timberline to advance northwards by many meters each year, with bushes encroaching on marsh and tundra. Warmer conditions also mean reindeer can no more cross the ice sheets to graze northern grasslands and prevent them from overgrowing. 8 butterfly varieties are at risk of extinction in this area, including the fritillary of Freyja and the Arctic ringlet.

“The biggest living space for all these pollinators is grassland rich in flowers and that is vanishing rapidly across the European continent because of all these reasons,” said Martin Warren. “The encouraging aspect is that so many people care now and there’s a lot more awareness. Under the European Union nature restoration law, all member countries have to turn around the drop in pollinators by the year 2030, and they are going to have to start doing something. There are property owners who are involved. It is hoped they can get the encouragements that will help them on their way.”

According to the coordinator, there is “easy opportunities” in terms of steps for pollinating insects which will not lower agricultural output – and might boost it – such as growers establishing bloom-filled edges around their farmland.

Jessika Roswall, portrayed the protection status of non-managed bees, butterfly species and other pollinating insects as “dire”.

“Urgent and collective action is needed to address this danger. Along with member states, the Commission of the European Union has put in place an EU-wide monitoring system for pollinating insects based on the European Union nature restoration legislation, which will help to track our progress. Now, we need to focus on application and partnership with member countries to protect our pollinating insects,” she said.

The publication of the assessments on bees and butterflies follows the pioneering EU-wide evaluation of hoverflies, a further crucial pollinating insect category. Published in 2022, it showed that over one-third of all hoverfly types in Europe were at risk of extinction.
